Till the early part of the last century, cases of Spinal Cord Injuries
invariably ended fatally within a few weeks of the injury, if not at the
time of trauma itself. A radical change in the approach to a patient with
SCI occurred soon after the Second World War. The surgical techniques were
developed during the 1950s and 60s. The last two decades brought in
significant advancements in Spinal Injury Management including
methlyprednisolone and GM1 therapy, intracthecal baclofen pump, titanium
cage for vertebral repair, delayed decompression for restoring function,
ileal conduits, stents and artificial sphincters for bladder and bowel,
sacral anterior root stimulator, tendon transfers to restore hand grasp
strength, etc. It also brought in promising therapies like IN-1 antibody
stimulating regeneration drugs like 4 AP improving in people with chronic
spinal injury and neurotrophin-secreting fibroblast transplants. Today, a
spinal surgeon has a significant armamentarium with which to tackle the
problem of SCI.
The future of SCI Management lies in-
- Regenerative therapies like axonal growth inhibitor blockade (Anti-Nogo
antibody IN-1, Nogo receptor blockers, chondrointinase), purine nucleotides
(inosine, AIT-082), therapeutic vaccines (spinal cord homogenate vaccine),
cell transplants (activated macrophages, fetal stem cell transplants,
olfactory ensheathing glia), electrical stimulation, PD4 inhibitors (rollipram),
neurotrophins (NGF+BDNF+NT3).
- Remyelinative Therapies like schwann cell transplants, oligodendroglial
cell transplants, stem transplants (mouse, porcine & human fetal), Olfactory
unsheathing glial transplants, Antibody therapies.
The current clinical trials are in the field of fetal cell transplants, 4AP,
activated macrophage transplants, porcine neural stem cell transplants,
alternation current electrical stimulation, AIT-082, Peripheral nerve bridge,
fetal stem cell and fetal stem cell olfactory ensheathing glial transplants.
Other promising therapies are in the filed of bio-feed back train W,
supported treadmill ambulation training, peripheral nerve bridges of
transected cords, spinal cord stimulator to activate central pattern
generators and experimental surgery (untethring, peripheral nerve
transplants, omentum transplant, hyperbaric oxygen and shark embryonic
transplants.
Each therapy has a limited probability of success. Multiple concurrent
clinical trials are likely to achieve some break through sooner or later.
